Abstract: The present invention relates to a molding made of foam, wherein at least one fiber (F) is located partly within the molding, i.e. is surrounded by the foam. The two ends of the respective fiber (F) not surrounded by the foam thus each project from one side of the molding. The foam is produced by polymerization of a reactive mixture (rM) comprising at least one compound having isocyanate-reactive groups, at least one blowing agent and at least one polyisocyanate.

Abstract: A process for the production of a polyamide is disclosed. The process for production of a polyamide (P) comprises mixing a first mixture (M1), which comprises at least one lactam and at least one catalyst, with a second mixture (M2), which comprises at least one lactam, at least one activator and at least one amine, to give a polymerizable mixture (pM) and then polymerization of the polymerizable mixture (pM) to give the polyamide (P). A polyamide (P) obtainable by the process of the invention is also disclosed, as well as moldings made of the polyamide (P).

Abstract: The present invention relates to a method for assembling moulded bodies. The invention also relates to a moulded body which comprises a foam and at least one fibre (F), the fibre (F) is within a fibre range (FB2) inside the moulded body and is at least once at least partially divided, wherein at least one fibre (F) is completely divided. The invention further relates to the thus obtained assembled moulded body, and to a panel with contains the assembled moulded body and at least one layer (S1). The invention further relates to a method for producing the panel and to the use of the assembled moulded body and the claimed panel, for example, as a rotor blade in wind turbines.

Abstract: Provided herein is a process for producing a polyamide (P) by reaction of a mixture (M) including at least one lactam (component (A)), at least one catalyst (component (B)), at least one activator (component (C)), and at least one oxazolidine derivative (component (D)). Further provided herein is the mixture (M) and the use of an oxazolidine derivative for increasing the crystallization rate of a polyamide (P). Also provided herein is the use of an oxazolidine derivative in a polyamide (P) for producing a molded article from the polyamide (P) for reducing the demolding time of the molded article and the use of an oxazolidine derivative for removing water from a reaction mixture (RM).

Abstract: The present invention relates to a process for producing a molding made from blowing agent-containing foam comprising at least one fiber (F), wherein the at least one fiber (F) is partially introduced into the blowing agent-containing foam. The two ends of the respective fiber (F) that are not surrounded by the blowing agent-containing foam thus project from one side of the corresponding molding. The present invention also provides the molding as such. The present invention further provides a panel comprising at least one such molding, produced by the process according to the invention, and at least one further layer (S1). The present invention also provides for the production of the panels of the invention and for the use thereof, for example as a rotor blade in wind turbines.
